This is what Chomsky wrote about Ponchaud's Cambodia book in June 1977

"Ponchaud’s book is serious and worth reading, as distinct from much of the commentary it has elicited. He gives a grisly account of what refugees have reported to him about the barbarity of their treatment at the hands of the Khmer Rouge."

So a book about the barbarity of treatment by the Khmer Rouge is "serious and worth reading". That is what Chomsky actually wrote back then if anyone is actually curious. Does not sound like what you claim he was saying.
